I'm wanting to build a set of retro wheelie bars for my 750 drag bike. Not as long as modern but functional (just in case) I'm thinking about 4'. Anyway I'm wondering about the diameter, what size chrome moly was used back in the day?
One thought is to make them telescope together to get them out of the way when not in use. Then a pit pin to hold them into place.
If I use .058 wall, the sizes slip into each other in 1/8" increments.
Of course skateboard wheels, wasn't that what they were originally?
